Oslo-based designer Hallgeir Homstvedt straddles the line between home and work with his armchair's strictly curved exterior and softer contours inside. A thick seam sweeps along the edge, a point of demarcation in the fully upholstered Arc, with its wide selection of fine leather and fabric options. Set on a wood platform structure edged in solid oak or walnut, the seating has matte, powder-coated steel legs, an HR foam seat and a solid wood internal frame.
